DETAILED DESCRIPTION

This description provides exemplary embodiments only, and is not intended to limit the scope, applicability or configuration of the mobile computing device, system, and method for location-based security of the present disclosure. Rather, the ensuing description of the embodiments will provide those skilled in the art with an enabling description for implementing embodiments of the mobile computing device, system, and method of the present disclosure. Various changes may be made in the function and arrangement of elements without departing from the spirit and scope of the disclosure as set forth in the appended claims. Thus, various embodiments may omit, substitute, or add various procedures or components as appropriate. For instance, it should be appreciated that in alternative embodiments, the methods may be performed in an order different than that described, and that various steps may be added, omitted or combined. Also, features described with respect to certain embodiments may be combined in various other embodiments. Different aspects and elements of the embodiments may be combined in a similar manner.

With reference to FIGS. 1 and 2, exemplary embodiments of the present disclosure provide a system and method of location-based security, in which RFID components 210 (e.g., RFID tags) removably or fixedly affixed to a mobile computing device 200 comprise microcontrollers (e.g., at least one hardware processor), and the communications infrastructure 206 (e.g., internal and external serial buses) of mobile computing devices 200 exchange location information between the RFID components 210 and the firmware and operating system(s) 232 of the mobile computing device 200. As used herein, a mobile computing device 200 includes at least one hardware processor 204 configured to execute computer-readable programs and an operating system 232 tangibly recorded on a non-transitory computer-readable recording medium (“memory”) 208 (e.g., ROM, hard disk drive, optical memory, flash memory, etc.). Examples of a mobile computing device 200 include a laptop, tablet computer, smartphone, etc. as known in the art.

FIG. 1 is a block diagram of components of a system for location-based security according to an exemplary embodiment of the present disclosure. In FIG. 1, the mobile computing device 200 is shown as having an RFID component 210 affixed thereto. The RFID component 210 may be removably or fixedly affixed to the mobile computing device 200. For example, the RFID component 210 may be comprised within the housing containing the electronic circuitry of the mobile computing device 200. In an exemplary embodiment, the RFID component 210 may have its own hardware processor 214 separate from the hardware processor(s) of the mobile computing device 200. In addition, the RFID component 210 has its own non-transitory memory 212 (e.g., ROM, hard disk drive, optical memory, flash memory, etc.) separate from the memory 208 of the mobile computing device 200, and a transceiver 220. In an exemplary embodiment, the RFID component 210 does not have its own hardware processor 214, but contains the memory 212 and the transceiver 220. The RFID component 210 may be passive, active, or battery-assisted passive. An active RFID component 210 has an on-board battery and periodically transmits a signal containing a data message (the message can include, e.g., identification information of the RFID component, etc.). A battery-assisted passive RFID component 210 has a small battery on board and is activated when in the presence of an RFID reader 100. A passive RFID component 210 is cheaper and smaller because it has no battery; instead, the RFID component 210 uses the radio energy transmitted by the RFID reader 100. The RFID component 210 contains at least two parts: an integrated circuit for storing and processing information, modulating and demodulating a radio-frequency (RF) signal, collecting DC power from the incident reader signal, and other specialized functions; and a transceiver 220 (e.g., antenna) for receiving and transmitting the signal. In an exemplary embodiment, the transceiver 220 can include two antennas in different polarizations such as linear and circular or horizontal and vertical. A single antenna can also be used. The RFID component 210 can operate, for example, in a frequency range between 860 and 960 MHz. The sensitivity of the antenna is important to the operation of the RFID component 210, and a minimum receive gain of the antenna greater than −2 dB should be maintained to ensure proper operation. In an exemplary embodiment, the antenna provides a roughly omni-directional radiation pattern. Due to regional banding of the ˜900 MHz ISM frequency space, the antenna(s) may be regionally designed. For instance, the North American ISM band is 902-928 MHz. With a transmitter at 28 dBm complying with FCC and UHF RFID Gen2 Specifications, this should yield a free space range of approximately 20 meters.

The RFID component 210 information (i.e. tag information) is stored in a non-volatile memory, e.g., memory 212. The RFID component 210 includes either fixed or programmable logic for processing the transmission and sensor data, respectively. In an exemplary embodiment, the RFID component 210 includes an Impinj MonzaX-8K Dura RFID integrated circuit or similar integrated circuit. FIG. 1 illustrates only one RFID reader 100 and RFID component 210 for clarity of illustration. However, it is to be understood that several RFID readers 100 may be equipped in a room or other area to which the mobile computing device may be carried. An RFID reader 100 transmits a radio signal, which may be encoded, to interrogate the RFID component 210. The RFID component 210 receives the message from the RFID reader 100 and then responds with its identification information. FIG. 3 shows an exemplary architecture of an RFID reader 100. The RFID reader 100 contains a non-transitory memory device 302 that can store the proximity signal (which can include the location data and/or a control policy), a hardware processor (e.g., CPU) 300, and a transceiver 304.

The RFID reader(s) 100 send a proximity signal (e.g., location-related information includes, for example, geographic coordinates, configured zones, and/or proximity information)) to the RFID component 210 embedded within or affixed to the mobile computing device 200, indicating the defined physical location of the RFID reader(s) 100 and/or the mobile computing device 200. The location information can be transmitted to the RFID component 210 while the mobile computing device 200 is in both the powered-on and powered-off states. The message stored in the RFID component's memory 212 is accessed by the hardware processor 214 of the RFID component 210. The hardware processor 214 serves three functions: 1) processes the location information provided by the RFID component 210 against corresponding control or management policies to determine the appropriate power state for the mobile computing device 200; 2) communicate with the power controls of the mobile computing device 200 to manage power states (e.g., force power off, enable power on, and disable power on); and 3) pass the location information to the mobile computing device's serial buses 206. In an exemplary embodiment, the RFID reader 100 can adjust its transmission frequency to avoid standard frequencies.

An operating system 232, one or more applications 234, and one or more hypervisors 236 can be stored in the memory 208.

In an exemplary embodiment, the data may be configured in any type of suitable database configuration, such as a relational database, a structured query language (SQL) database, a distributed database, an object database, etc. Suitable configurations and storage types will be apparent to persons having skill in the relevant art.

The mobile computing device 200 may also include a communications interface 224. The communications interface 224 may be configured to allow software and data to be transferred between the mobile computing device 200 and external devices. Exemplary communications interfaces 224 may include a modem, a network interface (e.g., an Ethernet card), a communications port, a PCMCIA slot and card, etc. Software and data transferred via the communications interface 224 may be in the form of signals, which may be electronic, electromagnetic, optical, or other signals as will be apparent to persons having skill in the relevant art. The signals may travel via a communications path 226, which may be configured to carry the signals and may be implemented using wire, cable, fiber optics, a phone line, a cellular phone link, a radio frequency link, etc.

Computer program medium and computer usable medium may refer to memories, such as the memory 208 and the memory 212, which may be memory semiconductors (e.g., DRAMs, etc.). These computer program products may be means for providing software to the mobile computing device 200. Computer programs (e.g., computer control logic) may be stored in the memory 208 and/or the memory 212. Computer programs may also be received via the communications interface 224.

Lastly, the mobile computing device 200 may also include a display interface 202 that outputs display signals to a display unit 230, e.g., LCD screen, plasma screen, LED screen, DLP screen, CRT screen, etc.

According to an exemplary embodiment, the location information provided through the mobile computing device's buses 206 can be integrated with either a hypervisor 236 or a native operating system 232 using a device driver.

Hypervisors 236 allow for the control of hardware of the mobile computing device 200 and guest virtual machines. Location-based security can be integrated in the hypervisor control domain directly or be installed as a guest virtual machine that interfaces with the hypervisor control domain.

Location-based security can be configured with rules to manage the hypervisor control domain using the desired automated response associated with various defined locations. Virtual machines, network interface cards, device power, USB ports, cameras, microphones, and other device hardware can be enabled or disabled based on defined policy rules.

The hypervisor 236 is configured to further distribute the location information to guest virtual machines running on the host machine.

The operating system(s) 232 of the mobile computing device 200 can receive RFID-based location information from either the serial buses 206 directly, if running as a native operating system 232, or as a pass-through from the hypervisor 236, if running on a guest virtual machine. The location-based security techniques of the present disclosure integrate with the operating system(s) 232 to control access to device hardware and device power states using the defined policy rules. Access to one or more applications 234 and one or more files stored or running on the operating system(s) 232 are also enabled or disabled using the device management functionality of the location-based security system and method of the present disclosure.

The exemplary architecture of FIG. 8 allows for multiple User VMs to be run in the future. The hypervisor is used to isolate the user VMs from hardware as defined in the control policy, ensure a secure networking environment and cryptographically isolate VMs from each other. In the exemplary architecture of FIG. 8, a network VM can encapsulate both of the layers of encryption and have direct access to the network interface.

FIG. 9 is a block diagram illustrating an exemplary architecture in which virtual systems management (VSM) can be used to dynamically manage hardware available to the User OS (USB devices, webcam, microphone, Bluetooth, etc.) and provide secure networking based on the policy issued over RFI D.

In an exemplary embodiment shown in FIG. 2, the mobile computing device 200 includes the memory device 208 having computer-readable instructions tangibly recorded thereon. The mobile computing device 200 can also include a hardware processor 204 configured to execute the computer-readable instructions recorded on the memory device 208. The mobile computing device 200 can also include an RFID component 210 that includes a transceiver 220 (e.g., an antenna) configured to receive a proximity signal from at least one RFID reader 100 when the RFID component 210 is within a predetermined range (e.g., within a couple feet or meters) of the at least one RFID reader 100. The predetermined range can be configured based on (1) the processing and/or telecommunication capabilities of the mobile computing device 200, RFID component 210 and/or RFID reader(s) 100, and/or (2) based on selectable distances (e.g., 10 feet, 20 feet, 30 feet) for specific control objectives, and/or (3) location restrictions such as the physical size of a room, building, or segment of a building (e.g., the second floor of the building). The mobile computing device 200 can also include a memory device 212 configured to store the proximity signal. In an exemplary embodiment, the hardware processor 204 is configured to, upon executing the instructions recorded on the memory device 208, control at least one operation of the mobile computing device 200 in accordance with the proximity signal received by the transceiver 220 of the RFID component 210 from the at least one RFID reader 100.

In an exemplary embodiment, the hardware processor 204 is configured to control at least one of: (1) at least one hardware component (e.g., memory device 208, display interface 202, camera 216, microphone 218, peripheral interface 222, communications interface 224, ports 228, etc.) of the mobile computing device 200; (2) at least one operating system 232 recorded on the memory device 208; (3) at least one hypervisor 236 recorded on the memory device 208; and (4) at least one application program 234 executable on the mobile computing device 200.

In an exemplary embodiment, the proximity signal includes a control policy including identifications of operations of the mobile computing device 200 that are performable (e.g., by the mobile computing device 200). For example, according to the control policy, the hardware processor 204 is configured to enable or disable access to at least one of an executable application 234 stored in the memory device 208, a file stored in the memory device 208, at least one operating system 232 of the mobile computing device 200, and a peripheral hardware component (e.g., external hard drive, server, external disk drive, etc.) with which the mobile computing device 200 is configured to communicate. That is, when the mobile computing device 200 is within a certain range of the RFID reader 100, the hardware processor 300 causes the transceiver 304 to send the proximity signal, which includes the control policy, to the RFID component 210. Because the control policy identifies which operations, devices, files, or applications can be accessed and/or used by the mobile computing device 200, the hardware processor 204 is able to control the operations and/or access to devices, files, applications, etc. of the mobile computing device 200 in accordance with the control policy that was received. In an exemplary embodiment, a server can store multiple control policies for individual RFID readers 100 and/or mobile computing devices 200, and each control policy can be sent to the appropriate RFID reader 100 to which the control policy applies. The control policies can be updated on the server, and the updated control policies can be pushed by the server to the appropriate RFID readers 100. When an RFID reader receives its intended control policy, it is saved in the memory 302 of the RFID reader 100 where it can subsequently be transmitted to the RFID component 210 of the mobile computing device 200 by the transceiver 304.

In an exemplary embodiment, the proximity signal includes location-related data indicating a current physical location of at least one of the RFID component 210 and the at least one RFID reader 100. In an exemplary embodiment, the location-related data can identify the reader that transmitted the proximity signal (by name, MAC ID, serial number, code, room name, etc.). In an exemplary embodiment, the location-related data can identify a defined zone (i.e. an area of space in which the mobile computing device 200 is located). In an exemplary embodiment, the location-related data can be geographical coordinates.

In an exemplary embodiment, the memory device 208 has recorded thereon a control policy for the mobile computing device 200, the control policy including identifications of operations of the mobile computing device 200 which are performable based on the physical location of the mobile computing device 200. The hardware processor 204 is configured to compare the location-related data with the control policy, and determine which operations of the mobile computing device 200 are permitted to be performed based on the comparison.

In an exemplary embodiment, based on the comparison of the location-related data with the control policy, the hardware processor 204 is configured to control a power state of the mobile computing device 200. Exemplary power states include: power off, power on, sleep mode, hibernate mode, etc.

In an exemplary embodiment, based on the comparison of the location-related data with the control policy, the hardware processor 204 is configured to control access to at least one hardware component (e.g., memory device 208, display interface 202, camera 216, microphone 218, peripheral interface 222, communications interface 224, ports 228, etc.) of the mobile computing device 200.

In an exemplary embodiment, based on the comparison of the location-related data with the control policy, the hardware processor 204 is configured to enable or disable access to at least one of an executable application 234 stored in the memory device 208, a file stored in the memory device 208, at least one operating system 232 of the mobile computing device 200, and a peripheral hardware component with which the mobile computing device 200 is configured to communicate.

In an exemplary embodiment, the transceiver 220 of the RFID component 210 is configured to receive an update signal from at least one RFID reader 100, the update signal containing an update to at least one of the identifications included in the control policy recorded on the memory device 208. The hardware processor 204 is configured to update the control policy recorded in the memory device 208 in accordance with the update contained in the update signal.

In an exemplary embodiment, at least one of the control policy and the proximity signal are encrypted. Thus, the location data received from the RFID reader 100 can be encrypted. For example, the control policy and/or the proximity signal can be encrypted using an AES-256 GCM algorithm and signed with an ECDSA Curve P-385 signature or with a similar encryption scheme. In an exemplary embodiment, certificates for the ECDSA process are distributed as part of the system configuration and are assigned based on organizational region. Policy signatures can be generated, for example, on the message bytes 0 to 927. In an exemplary embodiment, encryption is performed on the entirety of the message bytes 0 to 1024 after the signature is generated. Pre-distributed key material unique to each RFID tag is stored in the device TPM and on a server. The key material is hashed with a NONCE that is part of the RFID transmission to generate individual session keys for each of the written policies. In an exemplary embodiment, a single policy can be used for both the UEFI/firmware of the mobile computing device 200 and operating system 232 of the mobile computing device 200, so both have cryptographic capabilities capable of decrypting the entire message and verifying the signature. Key storage can be handled in a TPM 2.0 capable TPM. In an exemplary embodiment, all messages of the RFID component 210 except for the NONCE(s) are encrypted, for example using the scheme above.

The messages used in the present disclosure can be stored on the memory device 212 of the RFID component 210. In an exemplary embodiment, the memory device 212 is 1,024 bytes in storage size, and stores the control policy along with a CRC16, ECDS curve P-384 generated signature and a 512 bit random NONCE unique to that configuration.

The at least one RFID reader 100 is configured to communicate wirelessly with the RFID component 210 of the mobile computing device 200 and transmit the proximity signal to the RFID component 210 of the mobile computing device 200 when the RFID component 210 is within the predetermined range. In an exemplary embodiment, at least one server is configured to transmit the update signal to the RFID reader 100 for updating the control policy recorded on the memory device 208 when the mobile computing device 200 is in communicative range with the RFID reader 100.

In an exemplary embodiment, a system includes the mobile computing device 200 and at least one RFID reader 100 configured to communicate wirelessly with the RFID component 210 of the mobile computing device 200 and transmit the proximity signal to the RFID component 210 of the mobile computing device 200 when the RFID component 210 is within the predetermined range.

In an exemplary embodiment, the memory device 212 has recorded thereon computer-readable instructions and a control policy for the mobile computing device 200, the control policy including identifications of operations of the mobile computing device 200 which are performable based on the location-related data of the received proximity signal.

In an exemplary embodiment, the RFID component 210 includes a hardware processor 214 configured to execute computer-readable instructions recorded on the memory device 212, compare the location-related data with the control policy, determine which operations of the mobile computing device 200 are permitted to be performed based on the comparison, and generate an operation signal identifying the operations of the mobile computing device 200 which are determined to be performable.

FIG. 4 is a flow chart diagram illustrating operations performed by an RFID reader 100 according to an exemplary embodiment of the present disclosure. According to an exemplary embodiment, the RFID reader 100 has a hardware processor 300 (e.g., CPU) configured to execute computer-readable software tangibly recorded in a non-transitory computer-readable recording medium 302 of the RFID reader 100. Executing the software, the hardware processor 300 constantly scans for available RFID components 210 (i.e., RFID components 210 in proximity to the RFID reader 100). An RFID component 210 can be in proximity of the reader when it is, for example, within a radius of several feet or meters. When the hardware processor 300 finds a RFID component 210, it begins a secure and signed transaction with the RFID component 210. The RFID component 210 transmits its current configuration and two random NONCE that are used to generated cryptographic keys and signatures. One NONCE is used to encrypt and sign the current configuration and location data, and the other is used to encrypt and sign any data that is pushed to the RFID component 210. The RFID reader 100, upon finding a RFID component 210, checks the current configuration, and validates it against what it thinks the configuration should be. If there is a discrepancy, the hardware processor 300 of the RFID reader 100 pushes the configuration and then re-rereads the tag to verify it was written correctly.

FIG. 5 is a flow chart diagram illustrating operations performed by the hardware processor 204 of the RFID component 210 according to an exemplary embodiment of the present application. In an exemplary embodiment, the RFID component 210 is a passive tag with an active low power processor enabling cryptographic functionality. In its memory 212, the RFID component 210 stores its current configuration (e.g., control policy) and two NONCEs for the RFID reader 100 to read. If the RFID component 210 receives an updated configuration from the RFID reader 100, it verifies the signature, decrypts the configuration and pushes it to the mobile computing device 200. If the mobile computing device 200 requests the current configuration at any point, it will also push the configuration.

FIG. 6 is a flow chart diagram illustrating operations performed by the hardware processor 204 of the mobile computing device 200 according to an exemplary embodiment of the present disclosure. The hardware processor 204 of the mobile computing device 200 executes a software program dedicated to interfacing with the RFID component 210. The execution of this software monitors any pushed configurations from the RFID component 210, decrypts them, and checks the signatures on them before setting up the policy locally on the mobile computing device 200. When the mobile computing device 200 is started (i.e., powered on), on boot the software requests the current status (e.g., control policy) from the RFID component 210 to set the initial boot policy.

The present disclosure provides that different operations can be performed with the mobile computing device 200 based on the mobile computing device's 200 presence in different areas having different security designations. FIG. 7 is a diagram illustrating exemplary scenarios according to the present disclosure in which the mobile computing device 200 (abbreviated as “host”) is outside an allowed area, enters an unsecured allowed area, enters a secured allowed area, and leaves an allowed area. For each of these areas, FIG. 7 illustrates the operations performed by the RFID reader 100 (top block), the RFID component 210 (middle block) and the hardware processor 204 of the mobile computing device 200 (lower block) executing the above-described software dedicated to interfacing with the RFID component 210.
